dc.description.abstract | [EN] Lignin conversion processes produce carbon-rich residues
[Oregui-Bengoechea et al. J. Anal. Appl. Pyrolysis 2015, 113, 713−722;
Zakzeski et al. Chem. Rev. 2010, 110, 3552−3599] that can be converted into
valuable materials such as magnetic activated carbons (MACs). Such ligninderived
MACs can be further used as functional substrates for hydrotreating
NiMo catalysts. In this work, we studied the activity of different NiMo-MACs
for the catalytic conversion of lignin in a formic acid/ethanol media (lignin-toliquid,
LtL, process). Two KOH-activated LtL hydrochars from eucalyptus
(MACE) and Norwegian spruce (MACS) lignins were used as catalyst supports. In addition, the activity of the resulting NiMo-
MACs, namely, C-MACE and C-MACS, was compared with a NiMo catalyst supported on a commercial activated carbon (AC).
At reaction conditions of 340 °C and 6 h, the best result was obtained for the NiMo-MACS with a yield of 72.2 wt % of oil and
21.1 wt % of organic solids. At 300 °C and 10 h, both NiMo-MAC catalysts displayed higher hydrodeoxygenation (HDO)
activities than their commercial counterpart, yielding considerably higher oil yields. The higher HDO activities are tentatively
assigned to the formation of NiFe species on the catalytic surfaces of the NiMo-MAC catalysts. In addition, the magnetism
exhibited by the C-MACS made it easy to recover the catalyst. However, a considerable loss of activity was observed upon
recycling due to a chemical modification of the catalyst surface. | es_ES |
